Quantum algorithm results are difficult to compare across papers and platforms. QEncode provides a fixed benchmark suite with signed certification so performance claims are reproducible and decision-ready.
Free to run yourself. Certified results available for publications and grant applications.

You don't have to run our pipeline to use QEncode. Knowing whether your energy is any good means comparing it against the exact ground state of the same active space — normally a PySCF install and a wait.
We ship those reference energies for all 16 suite molecules inside the package, so scoring imports no chemistry stack and needs no network.
pip install qencode-benchmark
import qencode
s = qencode.score(-7.9835,
molecule="LiH",
active_space=(4, 4),
optimizer="COBYLA",
ansatz="hea")
print(s.report())Returns the gap to exact diagonalisation, the certification margin, and whether your optimiser and ansatz make that margin fragile on another machine.
Different molecule choices, encodings, ansatz settings, and runtime assumptions make cross-study comparison unreliable. Without a fixed benchmark standard, teams spend time arguing about setup rather than measuring quality.
Identical molecule, encoding, and ansatz settings across every submission. No setup ambiguity.
SHA-256 provenance hash and Ed25519 signature. Every certified entry is independently verifiable.
Compare accuracy gap, circuit depth, and two-qubit gate count across all certified submissions.
All benchmark entries, reference energies, and run configs published in the open GitHub repository.

pip install qencode-benchmark, then qencode run --molecule H2. One command per molecule, no clone needed.
Share your JSON entry with the community, or apply for managed certification with a signed artifact.
QEncode runs the fixed pipeline, signs the result, and delivers a validation report.
Choose public leaderboard inclusion or private delivery only for grant and paper use.
If you need an independently signed benchmark receipt for a paper, grant, or hardware evaluation, QEncode offers managed certification with full provenance. The self-run path is always free.
Clone the repo, run the suite, and join the leaderboard. Certification available when you need signed results.
